Abstract : Salivary glands of adult female blackflies of known ages were examined by histological methods. These studies showed that each of the paired salivary glands consists of two parts: a reservoir composed of relatively small cells, and a U-shaped lobe composed of larger secretory cells. The secretory cells progressively accumulate a PAS-positive secretory substance during the first 48 h of adult life. The PAS-positive material is lost from the secretory cells when the blackfly takes a blood meal. During the first 24 h after a blood meal the secretory cells again synthesize some PAS-positive material, but in some individuals the resynthesis is still not complete after 72 h. Limited examination of the salivary glands of males was carried out. (Author)
